Geoscience Spatial Framework for 3D Geological Models

Geoscience Spatial Framework is a database for storing 3D modeled geological surfaces and volumes in a software-independent structure. It uses points defined by latitude/longitude pairs as its fundamental spatial unit and includes topological triangulation data to define surfaces and volumes. The framework, created by the British Geological Survey, allows models to be linked to descriptive attributes and integrated with other BGS datasets.

Use Cases

• Construct 3D geological volumes using the stored topological triangulation information between latitude/longitude points.
• Integrate modeled surfaces with external attribute datasets via the framework's linking capabilities.
• Analyze spatial relationships and model geometry based on the point-based data structure and triangulation data.
• Standardize and compare 3D models from different software packages using the independent data structure.

Strengths

• Provides a software-independent structure for 3D geological models, facilitating data integration.
• Includes topological triangulation data, enabling the reconstruction of surfaces and volumes.
• Designed to link models to a range of descriptive attributes and other BGS datasets.

Limitations

• The elevation component of the latitude/longitude points does not rigorously conform to the ETRF89 datum, introducing potential positional inaccuracies.
• Dataset is marked as 'mothballed', indicating it may be archived, unsupported, or not actively maintained.
• Specific scale, sample size, and geographic coverage of the stored models are unknown.
